SOLE CHANNELING AND SHAPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 245,712, dated August 16, 1881.

Application filed July 11, 1881. (No model.)

To all whom it may concern:

Be it known that I, OHARLEs W. GLIDDEN, of Lynn, county of Essex and State of Massachusetts, have invented a new and useful Improvements in Sole Channeling and Shaping Machines, of which the following description, in connection with the accompanying drawings, is a specification.

This invention has for its object the production of a practical machine to both channel and cut into sole-shape a piece of leather for the inner sole of a welted shoe.

Myinvention is an improvement 011 the class of machines represented in United States Patent No. 239,999, dated April 12, 1881, to which reference may be had, I having combined with the machine represented in the said patent a blade by which to trim and give ultimate shape to the edge of the sole, it havinga pattern applied to one of its faces.

In the machine herein represented the sole will be channeled and beveled at its edge so as to leave a Wale or ridge to which to secure the upper and welt, the distance of the said Wale from the edge of the sole being varied about the forepart and shank, and the edge of the channeled inner sole will be out vertically to give to the sole the shape of the pattern or bottom of the last on which it is to be applied, to thus avoid trimming the edge of the inner sole when applied to the last, as heretofore common.

My invention consists in various constructions of mechanism, producing a machine to channel, bevel, and trim soles, as will be hereinafter more fully set forth in the claims at the end of the specification.

Figure 1 represents a front side elevation of a machine containing my invention; Fig. 2, a rear side elevation thereof; Fig. 3, an enlarged top view of the edge-trimming attachment removed from the machine; Fig. 4, a side elevation of Fig. 3 5 Fig. 5, an under-side view of Fig. 3; and Fig. 6 a top view of the sole-pattern plate, to be applied upon one side of the leather to be made into a sole.

1n the drawings, Figs. 1 and 2, embodying my invention, I have shown a machine like that represented in the patent referred to, and

have herein designated the corresponding parts by like letters. 1

The frame parts A A of the machine will be of suitable shape to support the working parts. The part A of the frame, made as an arm, is pivoted to the part A by the bolt A The arm A has an ear, A provided with a stud, A upon which is placed a pinion, A having connected with its hub a handle, A by which the machine is operated. This pinion A engages and drives the toothed gears BC. The gear B is placed on shaft B, having its bearings in the frame part A, while the toothed gear 0 is secured to the shaft 0, having its hearings in the frame part A. Upon the forward end of the shaft G is placed the stock or sole support 0 it being loosely connected therewith by a feather, a, so that the said support may be moved longitudinally on the said shaft. The hub of the support (1 (see Fig. 2) receives about it the strong spiral spring 0 held in place thereon by a nut, 0 turned upon the screw-threaded end of the shaft 0, so that the pressure of the said spring tends to keep the support C pressed back against the roller a at the end of the slide bar a, connected with toggie-jointa a the center of which has attached to it the rod a which, in practice, will be connected with a suitable foot-treadle, (not shown,) the normal condition of the toggle-joint due to the pressure of spring C being that indicated in Fig. 2.

The slide bar a screw-threaded for a portion of its length, is provided with a nut, 2, which controls the extreme forward movement ofthe slide bar and roller a by abutting against a rigid part of the frame-work, and also with nuts 3 l, which are made to pinch the shank m of the carriage M for the edge-trimming blade 22, the said carriage being made laterally movable with the slide bar a and support 0 This carriage M is composed of the slide m fitted in guideways of the frame A; of a bed-plate, m fixed thereto and provided with a circular groove, 23; of an adjustable plate, at, and a suitable holder, m to hold the edgetrimming knife or blade 22. The groove 23 of the bed'plate receives the nut or head 24 of a bolt, 30, carried by the adjustable plate m This bolt has a nut, 25, which may be turned to draw the bolt upward and clamp the adjustable plate securely'in adjusted position with relation to the bed-plate; or, when the nut is loosened, the adjustable plate may be turned thereon to enable the edge of the blade 22 to be presented to the leather at a greater or less inclination, as may be desired.

The forward end of the adjustable plate m has a downward projection, 29, curved at its rear side to fit a corresponding curved seat (see Fig. 5) made at theforward end of the bedplate m the said projection and seat serving as a pivot and bearing, about which the plate m may turn.

The holder m has at its under side a rib, 31, to enter a corresponding groove in the plate m and near its front end the holder has a pro jection,32, to extend under a projection, 33,

at the front end of the plate m The front end, 28, of the holder always rests close to or against the rear side of the support as does the edge-gage in the patent referred to, and is extended somewhat above the top of the support 0 to serve as a gage for the edge of the sole-pattern 48. The ear 34: of the holder serves to support the edge-trimmin g blade or knife 22, it being held in place by the set-screw 27. The holder is adj ustably secured upon the plate m by the screw 26,screwed into the said plate and extended through a slot, 35, in the holder. (See Fig. 3.) The holder will be adjusted' on the plate 022, in the direction of the slot 35, as the blade is reduced in width by grinding. This carriage M takes the place of the edge gage shown and described in the said patent, and is moved horizontally by the slide-rod a in unison with the support 0 as was the edge-gage in the said patent.

The blade 22 cuts the edge of the leather for the inner sole at right angles to its thickness, and at the proper distance from the Wale left by the blades or cutters of, and gives ultimate shape or outline to the edge of the inner sole, in accordance with the shape of the pattern. As the sole-support is moved horizontally, and the blade f is raised or lowered to form the wale further into the shank of the sole, and also insure the same thickness of sole-edge, the holder and blade 22 are also moved horizontally.

The arm A of the machine has a downwardly-extended leg, A (Shown as broken out in Fig. 1 to clearly exhibit the carriage M.) The lower end of this leg is received within a slot at the rear of an upright ear, A", broken off in Fig. 1. This leg A of the arm A, held down by the stress of the spring D on the rod 61 connected by bolt 01 with a backwardly extended part, 00 of arm A, rests upon stop (1 the latter thus controlling the descent of the arm A and the cutters and feed-Wheel carried by it. A lever, D, (see Fig. 1.) has its short end interposed below the leg A", and when brought into the position shown in that figure acts upon the lower end of the leg and lifts the forward end of the arm A and its attached parts, to permit the work to be introduced or removed. The arm A has a depending bracket, D herein shown as connected therewith by a bolt, 1), the said dependin gbrackethaving adj ustabl y j oin'ed with it the shank 12 which at its lower end has an adjustable bearing controlled by the screw b the said bearing 1) receiving the rod N, which carries the channeling-cutter c, it being held adjustably upon the said rod by the nut c. The presser-foot dis connected with the bracket D by the screws 8, in such manner that the spring d may act to hold the said presser in a yielding manner in contact with the sole being channeled.

The channel-cutter can be raised and lowered vertically with relation to the support 0 and may be secured in proper adjusted position by means of the screws d according to the depth to which itis desired to cut the channel, and the descent of the lower end of the arm A, which carries the cutters and feedwheel, is regulated by the stop d (see Fig. 1,) against which the lower end of the leg A is permitted to strike.

111 this machine I employ'two presser-feet, d 6, one at each side of the feed-wheel E. The one, 6, at the inner side of the said wheel next the beveling-cutter f is held in a yielding manner by the spring 6 The feed-wheel E, preferably serrated at its edge, is connected directly with the end of the shaft B, (see Fig. 2,) the said shaft, at its forward end, being supported in a movable bearing, g, acted upon by a spring, g, controlled as to its strength by a spring-regulator, (shown as a screw,) 9

The edge-beveling cutter f has its shank connected by screw f with the blade-carrier f fitted into a slot or groove in the end of the carriage f, the. said carriage being loosely attached by a headed bolt, f to a guide-block, h, the said bolt f being extended loosely through a curved slot in the said guide-block. This carriage f is provided with pins 10 12, (see Fig. 2,) having suitable rolls, which are extended into the circular groove 13 made in the guide-block h, and connected with the carriage, or with the screw it thereon, is a link, h which at its lower end will be attached to a treadle. The'tail-piece k of the carriage will strike the adjusting-screws 15 16 as the carriage is moved in one or the other direction in its curved path, the said adjusting-screws being set to correspond with the thickness it is desired to retain for the edge of the sole being operated upon. The screws 15 16 will be set to limit both the upward and downward positions of the said carriage f to thus enable the said blade to cut the edge of the sole at the proper inclination about its fore part and in the shank. As the carriage f is moved up to lower the first end of the blade f and out farther into the shank the support is moved horizontally inward. The blade f and its carriage, disconnected from the support and from the parts carrying the channel-cutter and feedwheel, are moved, as described, in a curved path. 7

The carriage f, as it will be noticed, has its fulcrum f movable or variable in position, so the carriageand blade f do not oscillate or move in the arc of a circle about a stationary or fixed fulcrum. This variable fulcrum affords greater facility in controllingthe bevel about the edge of the sole.

The leather to be channeled, beveled, and trimmed to fit the bottom of the lastand constitute a sole for a Welted shoe has the soleshaped pattern-plate 48 attached to it by means of suitable spurs or pins, 49, of the patternplate, which pins penetrate the solo at one side. The edge of the plate 48 will be held closely against the front end, 28, of the portion tion m of the carriage M, the said end 28 constitutin g an edge-gage for the sole pattern plate as the latter rests upon the support 0 the edge of the leather or sole beyond the edge of the said pattern-plate being cut off by the blade 22.

I claim- 1. The channeling and ed ge-bevelin g cutters and horizontally-movable sole-support C combined with the edge-trimming blade and edgegage 28 for the sole-pattern plate, the said blade and edge-gage being made horizontally movable in unison with the sole-support, substantially as described.

2. The sole support 0 its holding-shaft, rod (i and actuating devices to move the said support laterally, combined with the carriage having the edge-gage for the sole-pattern and with the ed ge-trimming cutter to act upon and trim the edge of the sole, substantially as described.

3. The edge-beveling cutter, its pivoted carriage, and stop to control the upward and downward position of the said beveling cutter when beveling the sole at different angles about its fore part and shank, combined with the solesupport 0 and the horizontally-movable carriage having an edge-gage, 28, and with the edge-trimming blade22, substantially as described.

4. The slide m and bed-plate m combined with the adjustable plate m, the holder m thereon, and the edge-trimming blade 22, substantially as described.

5. The rotating sole-support the channeling and edge-beveling cutters, the feed to bear upon the sole directly at the top of the Wale to .be left between the channeling and edgebeveling cutters, and one or more resser-feet, combined with the edge-trimming blade 22 and the carriage having an edge-gage, 28, sub stautially as and for the purpose described.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.
